10 Claims.

This invention relates to improvements in cash registers or accounting machines of the key-operated type and is more particularly related to improvements in locking mechanism for controlling the automatic selection of totalizers and their associated devices for operation.

One of the several objects of this invention is to provide novel means for automatically selecting one totalizer for actuation when another totalizer is locked against such action.

Another object is to provide means for automatically selecting one totalizer and its associated devices for actuation when another totalizer and its associated devices are locked against such operation.

A further object is to provide a plurality of lock-controlled devices, one for each totalizer selecting key, for locking against operation any selecting key and its corresponding totalizer and associated devices, and to thereby effect the automatic selection of another totalizer and its associated devices for operation.

A still further object is the provision of a separate locking construction, comprising adjustable means under control of lock and key, which means when moved to a certain one of its various positions of adjustment releases the locked totalizer selecting keys and simultaneously effects the automatic selection of a certain one of said totalizers and its associated devices for operation.

Another specic object is to provide means for operating the machine on an automatic open keyboard with respect to registering in one total- 35 izer, and on an optionally open keyboard with respect to registering in another totalizer.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essen- 40 tial elements of which are set forth in appended claims, and a preferred form of embodiment such as hereinafter described with reference to the drawings which accompany and form part of the specification.

General description The present invention is shown applied to a 30 key-operated type 01"' cash register, such as fully shown and described in United States patents granted to Charles W. Green, Nos. 1,707,188, 1,842,546 and 1,920,374, issued March 26, 1929, January 26, 1932, and August 1, 1933, respectively. Only such parts of the machine as are directly involved in the present invention will be described herein, as reference may be made to the patents mentioned for any detailed information concerning the construction and operation of the rest of the machine.

While this invention has been shown applied to a cash register of the type illustrated and described in the above cited patents, it is to be understood that the invention is capable of being applied to or embodied in other forms of cash registers and accounting machines without departing from the spirit of the invention.

As is shown in the patents above referred to, machines of this type have previously been provided with a plurality of totalizers adapted to segregate the transactions entered in the machine according to separate departments, classes or clerks. Usually one of the totalizers is normally set for operation so that when the amount Y simultaneously adjusts for engagement the se- Y lected totalizer and its associated devices.

. each totalizer selecting key, adapted to selective- Such machines are sometimes vprovided with a Y plurality of selecting keys, one for each totalizer.

While it is not essential that such a key be provided for each totalizer, especially where one of the totalizers is normally set for operation, it

' is found desirable to do so primarily Yfor the purpose ofv lifting the key coupler to the coupling position so that the amount keys can be attached thereto successivelyV as desired. By a careful manipulation of one or more of the amount keys the key coupler can also be lifted to this particular .position to attach other amount keys Vto the coupler, but there is nothing Vto prevent the movement of these keys beyond the coupling point or to serve as a stop when this point is reached. Itis often desirable, therefore, to provide a separate selecting key for each totalizer so that when it is operated the coupler will be positively stopped at'the coupling position and will not be lifted beyond this point, such as Ywould be the case if an amountkey were operatedrtoo quickly. Y

There has been also employed in such machines special lock-controlled devices, one for ly lock against operation any selecting key and its corresponding totalizer without interfering with the usual operation of any other totalizer,

" and the provision of mechanism, comprising adjustable means under control of lock and key,

whereby the proprietor or other authorized persons can conveniently render ine'ective said lock-controlled devices for the totalizer selecting keys.

' vided with two totalizers.

Y The present invention includes all of the above` mentioned features in combination with novel means for eiectingl the automatic selection of any one of a plurality of totalizers and its associated devices for operation.

For the purpose of illustration, theV present invention is shown applied to a machine pro- These totalizers are so arranged that either one or the other may be brought into operative relation with the operating means,"so that the clerks may registerthe amounts of their sales independently. It is, moreover, Ydesirable that either one of the totalizers be capable of being engaged automatically Whenever any of the amount keys alone are operated, and that the other totalizer be placed in operation under the control of its respective selecting or clerks key which is operated in conjunction with the desired amount keys. It is also i desirable that means in the form of special transaction keys be provided for throwing out or disengaging the totalizer which has previously been e selected for operation.

In the present embodiment of the invention the upper totalizer has been-appropriated to receive the amounts registered bythe A clerk, while ,thelower or remaining totaliz'er is placed vunder the control of the Bf clerk. e

"While it is only essential that one clerks key be provided in the present machina'since the totalizer assigned to clerk A .is normally setV for operation, a separate clerks key has been provided for each totalizer in order torfacilitate the lifting and stopping of the key coupler in the coupling position so that the amount keys may more easily be coupled thereto.

The illustrativermachine is providedn with a plurality of lock-controlled devices, one for each totalizer selecting key, for locking against operation one or both of the totalizer selecting keys and their corresponding totalizers. Y

One selecting key and its corresponding totalizer may be locked against operation by means of its respective lock-controlled device, and at such time means is provided for automatically selecting the other totalizer and its associated devices for-operation.

The present machine is also provided with separate locking mechanism, comprising adjustable control means under control of lock and key, which meansl when moved to a certain one of its various positions of adjustment is adapted to render ineective not only the lockcontrolled devices for the totalizer selectingrkeys, but simultaneously effect the automatic selection-of one of the clerks totalizers and its associated devices for operation.

When both of the clerks keys are free to oper-x ate, means is provided for normally automatically selecting'one of said totalizers and its associated devices for operation when any oi the amount keys alone are depressed. n 1 K Under the arrangement provided in applicantfs machine, clerk A upon leavingV the store may lock his totalizer selecting key against operation, thereby preventing the selection of his totalizer and its associated devices'for operation, and simultaneously effect the adjustment of the other totalizer and its associated devices for automatic selection whenever any amount keys alone are depressed. Thus, it wnl'be seen that the ma.-

chine maybe made toV operate on an optionally open keyboard to register in either totalizer byA simply locking against operation the selecting key for the other totalizer.

Where machines are provided with lock-con- Y trolled devices forY lockingagainst operation the totalizer selecting keys and their corresponding totalizers, it sometimes becomes necessary for the proprietor or other authorized persons to 'effect a registration in the totalizer Vof an absent clerk. To provide for this contingency, the ad-V justable means under control of lock and key, heretoforev referred to, is adapted when moved into a certain one of its various-positions or adjustment to unlock either or both of the locked clerks or totalizer selecting keys, even though they may have been locked by one Vor both of the clerks'before leaving the store. The machine is Vnow in condition whereby the proprietor can It will thus be seen that if one or both of thev clerks keys and their associated totalizers are locked against operation through their respective lock-controlled device-s, movement of the adjustable means to a certain one of its variouslposi- Cil action keys 42.

tions of adjustment will not only render ineffective said lock-controlled devices by releasing the locked clerks keys, but will simultaneously and automatically condition the machine for operation on an optionally open keyboard to register in the A totalizer. When the adjustable means is moved from the position just referred to, the lock-controlled devices for the clerks keys are again rendered eifective.

It will be apparent that the adjustable means should be subject to the sole control of only the proprietor or manager of a particular store,'and for this reason the adjustable means is provided with a lock to which the proprietor or manager is the only one having a key.

Detailed description The present machine is provided with a cash drawer casing 3l (Fig. l) upon which is mounted a suitable metal base 32, which serves as a support for two vertical side fra-mes 33 and 34 (Fig. 10). These side frames are connected near the rear of the machine by a cross frame 35 and a tie bar 46 (Fig. 1) and at the front of the machine by a tie bar 36. Near the center of the machine a pair of intermediate frames 31 and 38 (Fig. 10) are provided to support a number of totalizing and printing elements, as will be more fully explained hereinafter. The rear ends of these intermediate frames are suitably supported by the cross frame 35, while their forward ends are connected to the tie bar 36.

The mechanism of the machine is enclosed in a suitable cabinet 39, provided with the usual Window (not shown) through which the indicators are visible. The portion of the machine which encloses the indicators is fully shown and described in the above mentioned patents. The contour of the cabinet is such as to properly enclose all the operating parts, with the exception of a few elements which extend to the exterior of the cabinet for the purpose of operating the machine, and otherwise controlling it, as will be later explained.

Operating mechanism The illustrative machine is of the key-operated type of cash register and is provided with a number of keys divided into groups of amount keys 4| (Fig. 10) and a special group known as trans- As all of the keys in each group are the same, it will suiiice to illustrate and describe in this application but one key in each group. In addition to these keys there is provided a plurality of special keys 43 and 44 known as clerks keys, the purpose of which is to control the selection of the totalizers and also act as coupler lifting keys.

f The amount keys 4l and transaction keys 42 are pivoted upon a rod 45 (Figs. l, 5, 6 and 10) extending transversely of the machine and journaled between the side frames 33 and 34. Resting upon the keys near their rear ends is a key coupler 41 journaled at 43 between the side frames. The key coupler has a flange or nose 49 cooperating at times with the usual notches (not shown) in the amount and transaction keys. When the outer ends of the keys are depressed the key coupler 41 is rocked clockwise and the flange 49 thereon enters said notches. The purpo-se of such key coupler mechanism is old and well known in the art and need not be discussed herein.

Connected to the right-hand end of the key coupler 41 is the usual vertical reciprocating rack plate (not shown) which is provided with rack teeth which alternately mesh with a gear fast to the right-hand end of a shaft 50 to impart thereto a rotary motion. This mechanism is also old and well known in the art and as it is shown and described in the previously mentionedpatents it is therefore not shown or described in this application.

FZcibZe-key coupler As is usual in a machine of the type used for illustration, there is provided a device for coupling amount or transaction keys to the key coupler at the beginning of their movement so that any desired number of keys may be successively depressed and coupled and then the depression of all of them completed by anyone to elfect the indication and registration of their combined value. This enables the operator to indicate and register with one hand a registration requiring the operation of two or more keys since it obviates the necessity of spanning several keys with his hands in order to secure the simultaneous operation of those keys.

For the purpose of raising the key coupler 41 to what is known as the coupling point any of the amount of special transaction keys may be employed, as above mentioned, but in the present instance the special keys designated as clerks keys are especially provided to perform this function. The clerks keys 43 and 44 (Fig. 10) are located at one end of the machine and are pivoted upon the rod 45 just as are the amount keys. Each clerks key is formed with a notch 5I (Fig. l) below the rear end of the key coupler. The forward edge of this notch is provided with a cam surface 52 which engages a cam edge 53 of a notch cut in the under side of the key coupler. The notch 5| in each of the clerks keys is adapted to receive the portion of the key coupler to the rear of the cam edge 53 when a clerks key is depressed to its coupling position. An edge 55 of the notch 5l provides a stop face which engages the rearward edge of the flange 49 of the key coupler and positively stops the motion of the key and key coupler. Thus when a clerks key is depressed the cam edge 52 will cooperate with the cam edge 53 and raise the key coupler to a partially elevated position where it will be stopped by the engagement of the ilange 4S with the edge 55 of the notch 5l and will be held in this position by the usual full stroke mechanism, (not shown), but provided in machines of this type.

However, when pressure is removed from the clerks key the rear end oi the key will drop back until a iinger 56 thereon rests upon the upper edge of an angular member 51 fastened to the key coupler. At this time, any of the amount keys may be slightly depressed to engage them with and raise the coupler still further. During this further operation the member 51 will be received by a cut-away portion 58 in the rear end of the clerks key. This mechanism is shown and described more in detail in the patent to F. L. Fuller, No. 1,729,338, dated September 24, 1929, to which reference may be made for a full showing and description thereof.

Differential mechanism The differential mechanisms and devices controlled by each of the various banks of amount eys are all similar in construction and operation so that a description of one will suflice for all.

Each of the amount keys is provided with an upwardly extending arm (not shown) carrying at its extreme upper Vend a stud which cooperates with an L shaped slotI 5ft formed in a cam plate 65 (Fig. 1). The cam plates S5, of which there is one for each key in a bank, are carried by a frame 66 loosely pivoted upon a transverse shaft 61 journaled between the side frames 33 and 34. Theslots 64V! are arranged in graduated order so that their cooperation with their 'respective amount keys serves to move the frame 65 differential extents corresponding to the value of the keydepressed. When the frame 6G is operated differentially by a key the studs associated with the undepressed amount keys in the same bank will play in arcuate portions of the slots 64 as shown in Ythe Green Patent 1,842,546 to permit lthe upward tilting of the frame 69 without interfering with the studs carried by the unoperated keys.

Itis to be understood that there is a differential frame BEnfor each denominational group of amount keys. Each differential frame 58 hassecured thereto and movable therewith a segmental rack 68 in constant engagement with a pinion (not shown) attached to the side of Veach item type carrier 69 mounted on av shaft 'i3 Yjournaled at its ends in the intermediate supporting frames 3'? and 38. Thus, it is evident that when the keys are depressed their corresponding racksV (E8 receive differentrdegrecs of movement so that the item type wheels '99 will be rotated correspondingly. When suitable impression means are actuated the item type wheels will print characters as shown in Fig. 10,'indicating the amount of the transaction entered in the machine.

` Totalizrers Located below the item type carriers 69 are two pivotally mounted totalizers, Ythe upper of which Y totalizers may be used for the purpose of regisv is, for convenience, designated asthe A totalizer and the lower asV the B totalizer. These tering amounts for separate departments or clerks or to segregate the transactions into any other two classes. The form of these totalizers is shown in the patent to C. W. Green, No. 1,707,188, above referred to, and they are therefore not shown in detail here.

VThe A totalizer comprises a frame Il (Fig. l).

pivotally mounted at 'i5 in the intermediate supporting frames 3l and 38 and carries a shaft 'l2 supporting a series of accumulating wheels 13, the peripheries of which are formed with raised'characters so as to effect printing upon a record strip.Y

Attachedto the accumulating wheels 'i3 are pinions i4 (Fig. 10) which are adapted at times to be brought into mesh with the segmental racks 68 by rocking the totalizer frame l about its pivotal point l5 (Fig. 9).

V'Ihe B totalizer, like the A totalizer, conv Totdlz'aer kselecting and engagingmechanism Either one of the totalizers provided in the present machine may be selectively controlled for operation by means of the clerks keys 43 and 44. However, the A totalizer is adapted to be nor- -mally selected for operation so that when the amount keys alone Vare depressed the amount will be added into said A totalizer. In order to select the B totalizer for operation, the B key 43 must be depressed which not only disables the mechanism which normally selects the A totalizer, but selects for operation a special type carrier, indicator,V special counter and cash drawer associated with the B totalizer.

When the A totalizer is 'selected for operation, mechanism is automatically operated which disables the B totalizer selecting means, and when the B totalizer is selected for operation means is provided for disabling the engaging mechanism associated with' the A totalizer.

Pivotally mounted upon a transverse shaft 80 (Figs. 1 and 9), located near the base of the machine, is a lever 8| carrying rollers 82 and 83 cooperating with a pair of complementary cams 84 and 85, secured to the main operating shaft 5U. The lever 8l is connected to a bail 99 mounted on the shaft 89. Integral with the bail 90 is a forwardly extending lever 9| (Fig. 19) carrying a pin 92. The prole of the complementary'oams 84 and 85 is such that the bail'9l) and lever 9| are givenan oscillatingrmovement during each operation of the machineand this movement is utilized'to effect the engagementY of the selected totalizer with the actuating racks.

Adjacent the left supporting frame 37 areY totalizer engaging slides 93 and 94 (Figs. 1,8 and 9). The A'totalizer engaging slide 93 is provided with a cam slot 95 which engages the A totalizer supporting shaft '12. In a similar manner the B totalizer engaging slide 9H is provided with a cam slot 96 cooperating with the totalizer wheel supporting shaft 'i1 Yof the B totalizer. Both of these slides are apertured at their upper ends to engage the item type wheel Supporting shaft l), while'at their lower ends the slides are slotted at 91 and 98 to engage the stud 92 carried by the lever 9i. Due to the above construction it will be evident that whenever a slide is reciprocated its cam slot cooperating with the associated Vtotalizer wheel supportingshaft will rock the related totalizer about its pivot to bring the pinions Yinto and out of engagement with the actuating racks 68. V Y Y Which one of the slides93 or 94 is reciproca-ated is controlled by plates 99 and 109. Pivotally mounted upon the pin 92 are two totalizer con-1 trol plates 99 and lli@ (Figs. 8,` 9 and 12), the one.

associated with the lower or B totalizer indicated by the reference numeral 99 and the one associated with the A totalizer by the reference numeral IDS. The plate lli is provided with a cam slotV lillV engaging a pin U32 carried by the A totalizer engaging slide 93. In a similar manner the B plate 99 is likewise provided with a cam Vslot H33 engaging a pin loll carried by the B engaging slide'l. The configurations of the camslots lill and ISS is such that when either plate 99 or |99 is .rocked about its pivot 92 from thernormal position (shown in Figs. 8 and 9) it willrtend to raise its associated slide Y93 Vor 94. The purpose of this mechanism is to neutralize the Vdownward movement of the slide 93 or Sli, as will appear later in the specication when the re- Y a similar manner the throwout bail |01 has integral therewith a downwardly extending arm H0 cooperating with a pin on cam plate 99. Each of the balls |06 and |01 is provided with rearwardly extending arms H2 and H3, respectively, to which are attached springs H4 and H5 which tend to retain the bails and cam plates in theirnormal positions, as shown in Figs. 8 and 9.

Associatedk with the B totalizer throwout bail |01 is a plate |20 (Fig. 1) provided with a shoulder |2| normally contacting a pin |23 attached to the side of the bail |01. The plate |20 is further provided with a lcam edge coacting with a pin |22 projecting from the side of the A key 44. Pivotally mounted on the rod 45 (Fig. 5) adjacent and associated with the B .key 43, is a lever |24 having a rearwardly projecting tail |25. Whenever the B key 43 is depressed the lever |24 is caused to move in unison with said key by a pin |26 carried by the key 43 coacting with the underside of the tail |25 of the lever |24. A pin |21 in the lever |24 is adapted to coact with the forward cam edge of a camv plate |28 which is provided with an extension |29 contacting the underside of the A throwout bail |06. From the above it will be noted that the A key 44, through its cam platev |20, operates the B throwout bail |01, while the' B key 43, through the pin |21 in its associate lever |24 and thecam plate |28, operates the A throwout bail |06.

Automatic engagement of "A totalizer The means for normally automatically engaging the A tctalizer whenever any of the amount keys alone are depressed will now be described. A pitman |29 (Figs. 1 and 9) having a lower bifurcated portion |39 embracing the pin 92 is pivotally connected at its upper end to a plate |3| pivotally mounted on the shaft |05 and having arearwardly projecting shoulder |32 adapted to Contact with the underside of the B throwout bail |01. Loosely mounted on the pin 92 is a cam plate |33 having a cam slot |34 which is adapted to cooperate with a pin |35 in the pitman |29. The cam plate |33 is connected to and adapted to move with the cam plate |00 by means of the pin |09. It will thus be evident that whenever the machine is operated by depression of any of the amount keys alone, the pin 92, through the cam plate |33, draws the pitman |29 downwardly and causes the shoulder |32 of the plate |3| to raise thev B throwout bail |01. Raising the B throwout bail |01 (Fig. 8) rocks the arm H0 and the control plate 99 counterclockwise. The -control plate, 99, Yby its coaction with the stud |04, tends to shift the link 94 upwardly. But this upward movement of the link 94 is neutralized by the 4lowering of the pin 92, which lowers the control plate 99 and, through stud |04, tends to lower the link 94. The rocking and lowering of the control plate 99 take place at the same time. The simultaneous .rocking and lowering movements of the control plate 99 result in no movement of the slide 94, and therefore the B totalizer is not engaged with the actuators when an amount key is depressed alone.

Should the B totalizer be selected for operation by depression of the`B key 43, the arm |08 of the A throwout bail |96, through its engagement with the pin |09, moves the cam plates |00 and |33 counter-clockwise. The control plate |00 acting on the stud |02 tends to shift the link y93 upwardly. But this upward movement of the link 93 is neutralized by the lowering of the pin 92, which lowers the control plate |00 and, through the stud |02, tends to lower the link 93. The rocking and lowering movements of the control plate |00 take place at the same time. The simultaneous rocking and lowering movements of the control plate |00 result in no movement cf the link 93, and therefore the A totalizer is not engaged with the actuators when the B key is depressed.

The control plate |33 also has two movements simultaneously; i. e., it is rocked by the arm |08 and lowered by stud 92 at the same time. This combined rocking .and lowering movement of the control plate |33 results in no movement of the pitrnan |29, and therefore the arm |3| is not rocked to operate the B yoke |01, arm H0, and control arm 99. Therefore in this case the control plate 99 receives only the lowering movement, which, by its contact with stud |04, lowers the slide 94 to engage the B totalizer with the actuators.

Clerks key locks The present machine is provided with individual locks for each of the clerks or totalizer selecting keys 43 and 44, which directly control the operation or non-operation of the clerks keys and their corresponding totalizers, each clerk being furnished with a key to the lock associated with his particular totalizer selecting key. Such an arrangement makes it possible for each clerk to have full control of his totalizer and when going off duty he is enabled to lock his particular clerks key and its corresponding totalizer against operation, without interfering with the operation of the other clerks key and its corresponding totalizer in the usual manner.

In the illustrative machine the A totalizer is normally automatically selected for operation, while special means is provided for automatically selecting the B totalizer whenever the A totalizer is prevented from being operated by locking the A totalizer selecting key 44 against operation.

Mounted in a bracket |40 (Fig. 1) secured to the side frame 33 are locks |4| and |42, of conventional type, having barrels |43 and |44, respectively, projecting through slots formed in the cabinet 39 to facilitate the insertion of the keys in the locks. The lock |4| controls the operation of the B key 43, while the lock |42 controls the operation of the A key 44.

The means for locking the B key 43 against operation will now be described in detail. Pivotally mounted on a stud |45 attached to the side frame 33 is a lever |46 the upper end of which is adapted to coact with a bolt |41 of the lock 4| associated with the B key 43. The lower end of the lever |45 is formed in the shape of a hook |48 (Fig. 6) having a surface |49 adapted to contact a pin |50 on the B key 43. A spring |5| (Fig. 1), attached at one end to the lever |46 and at its opposite end to a stud |52 supported in the side frame 33, serves to maintain the lever |46 in contact with the bolt |41 of the lock |4|. In the normal positions of the parts, as shown in Fig. 6, the surface |49 is in the rear of the pin |50, so that it will not interfere with the depression of the key 43. Rocking of the lever |46 by rotating the lock barrel |43 counter-clockwise to project the bolt |41 rearwardly carries the surface |49 thereof directly under the pin |50, thereby positively preventing depression of the B key 43.

The means for locking the A key 44 against Y |54 (Fig. l) the upper end of the lever |53 being forked to Vprovide a recess for a bolt |55 of. the lock |42. Part of the lever |54 is shown by dot and dash lines in Fig. 6. front of the lever |53 and is indicated by the dot and dash lines to give a better illustration of lever |53. The lower portion of thelever |54 is formed in the shape of a hook 52Y having a surface |58'vvhich is adapted to contact a pin |51 on the side of the A, key |44. A spring |158 fastened at one end to a pin |59 carried by the lever |54and secured at its opposite end to the stud. |52 normallyy retains the lower portion ofV the lever |54 and its surface |55 in a position just tothe rear of the pin |51 on the A key 44.

VWhen the lock'barrel |44 is turned the bolt |55-is projected rearwardly and rocks the lever Y|53 counterclockwise thereby causing its lower portionto contact a pin |58 carried by the lever |54 and move the latter to bring its surface |55 beneath the pin |51 onthe A key 44, thereby preventing the operation of the A key 44 and its corresponding totalizer. In this manner the AV key 44 is locked against depression.

Antomdtz'cengiagement of B totalz'eer In order that the B totalizer be automatically selected by'depression of theamount keys when the A totalizer is locked out, the lower end of the leverv |53 is adapted to coact with mechanism for effecting the automatic selection of the BY totalizer and'its associated devices for operation when any Yof the amount keys alone are depressed.

The lever v|53 is bifurcated at its lower Vend to loosely straddle a stud |54 on a coupling slide lei (Fig.Y Loosely mounted on the shaft 89 is an arm |58 providedV with a coupling slide |51V the upper end ofV which ts between a stud |58 on therear bifurcated portion of the lever |53 and the stud |53 on the coupling slide |6| to normally cause the lever |53 and slide l5! to` move in unison. The coupling slide 18| is provided with Va slot |52 near its forward end through which projects the rod 45, while near Vits rear end the slide |5| carries a pin |53 which projects through Vaslot |54 in the lever |24 mounted on the rod 45 adjacent the B key 43. The coupling slide |5| is provided at its rear end with a'h'ook portion |65 which, when the slide |51 is moved forward- 1v hooks over the ilange 51 of the key couplerlil. IThus, when the machine is operated with the parts in these positions, the key coupler 41 raises the slide together with the lever |24,"and by means of the pin |21 on the lever |24 coacting with the cam plate V|28 rocks the throwout bail 55, to prevent the engagement of the AF'totalizer, as previously described. VIn this way the B totalizer and its associated devices are auto--V matically selected for operationrwhen anyl ofthe amount keys'alone are depressed.

Item printing mechanism A suitable set of printing wheels is provided for printing the amount and character of the transaction, as wellV as the clerk making the entry, upon appropriate record material. Inasmuch as only one'of these type Wheels, the one adapted to print'characters designating the clerks keys,'is involved here, Vonly that portion of the mecha-v nism will be described. For a more detailed showing and description reference may be had to the patent to Green, No. 1,920,374, previously referredto'." i i f This lever |54 lies in Referring to Fig. 7, there will be seen the clerks printing wheel 89 which normally stands in a po-k sition to print the letter A. Upon operation of the Bkey 43 or the lever |24 associated therewith this type Wheel 69 is rotated to present the letter B to the printing line. The connections for this purpose comprise a pin |12 (Fig 7) mounted on the side of the lever |24, associated with the B key 43, Vand adapted to cooperate with a cam slot in a plate |13 secured to one'end of a bail V|14 loosely mountedon the shaft 80. The oppcsite end of the bail |14 carries an arm |15'to which is pivoted'the lower end of a link |16 the upper end of the link |16 being connected to an arm |11 of a clamp |18 secured to a sleeve |19 mounted cn the shaft 19. Rigid on the sleeve |19 is the clerks type wheel 69.V It will thus Vbe' clear that depression'of the B key 43 or the. automatic coupling of the coupler slide |6| with the coupler 41, through the raising of the lever |24 and its pin |12, rocks the plate |13 and arm |15 to elevate the link |18, thereby rocking the arm |11, clamp |18 and sleeve |19 to rotate the clerks. type wheel 59 to present the letter Bf to the printing line.

Shown directly above the'clerks type Wheel 69 is a printing hammer |80 carrying aplaten |8| nearV its forward end Which is adapted, Ywhen the machine is operated, to take an impression from the clerks type Wheel upon suitable record material This mechanism is fully shown and illustrated in, thel above mentioned patent to Green, No. 1,920,374,7and therefore is not shown or described in detail here.

Special counters The illustrative machine is provided with a series of consecutive number devices (Fig. 10) referred to hereinV as special counters, which are adapted to register the total number of Ytimes the machine has Vbeen operated by each clerk. There is one special'counter fo'r each clerks key.v The special counters are arranged in a horizontal line at the` front of the machine, just beneath the cabinet 39. These counters are of the regular multi-tined pawl deep-notch transfer type, well known in the art and described Yin many patents,

one of. which is the patent to Thomas Carney, No.'Y

' Vmounted on a shaft |89 supported at its ends inv brackets |99, only the left hand one of'which is shown secured to the tie bar 38.- YLoosely mounted Y on the/rod |89 (Figs. 4 and 11) is abail |9| carrying a spring-pressed multi-tined pawl Vmounted on a rod |93 supported at each endY in the sides of the bail |9|. When the bail |9| is rocked, the pawl |92 is adapted to engage the ratchets on the sides of the number wheels |81 and add a unit into the counter. The right-hand end of the rod |93 passes through and extends slightly beyond the right side of the bail |9| and is adapted to be engaged by a slotted'arm |94 fast on .a shaft |95 (Fig. l0). The shaft |95 is supported in the Vright-hand bracket (not shown, but like bracket |95) and in an ear (not shown) on thev tie bar Secured to the right-hand end of the shaft |95 is a' cam arm |96 (Fig. 4) having a cam slot vvolved here, only that mechanism will key 43 consists of a series of number wheels 204 (Figs. 1 and 10) each having attached to its side a ratchet 205 mounted on the shaft |89 adjacent the special counter associated with the A key 44. Also loosely mounted on the shait |89 is a bail 206 bearing a rod 201 carrying a spring-pressed multi-tined pawl 208 which is adapted, whenever the bail 206 is rocked clockwise, to engage the ratchets 205 and add a unit into the B special counter. The rod 201 passes through and extends slightly beyond the left side of the bail 206 and is adapted to be engaged by a biiurcated arm 209 rigidly mounted on a shaft 2 l0 supported by the bracket |90 (Fig. l0) and ears 2|| and 2|2 integral with the tie bar 36. Secured to the shaft 2|0 is a rearwardly extending arm 2|3. A link 2|4 connects the arm 2 I3 to the lever |24 (Fig. 5) associated with the B key 43.

It will thus be evident that whenever the machine is operated with either the B key 43 depressed or the coupling slide |6| coupled `to the key coupler 41, the forward end of the lever |24, through its connections with the key 43 and slide |6| is moved downwardly. Such downward movement of the lever |24, through the link 2|4 and arm 2|3, rocks the shaft 2|0 and arm 209 counter-clockwise, thereby rocking the bail 206 clockwise to engage the pawl 208 with the ratchets 205 and add a unit into the special counter associated with the B key 43. l

When the B counter is operated, means is provided for preventing the actuation of the wheels of the A counter. The means for accomplishing this consists of a pin 2|5 (Fig. 11) projecting from the left side of the pawl |92 of the A counter which is` adapted to cooperate with a disk 2 |6 rigidly mounted on the right side of the bail 206 associated with the B counter.

When the bail 206 is rocked clockwise during an operation of the B counter, the disk 2|6 contacts the pin 2|5 and holds the pawl |92 disengaged from the ratchets |88 of the wheels |81 of the A counter.

Indicatz'ng mechanism The machine disclosed in the present application is provided with indicating mechanism adapted to indicate to the front and to the rear, not only the amount of the transaction but the clerk making the entry as well as the nature of the transaction being performed. Since only the mechanism actuating the clerks indicators is nl; described.

The clerks indicators comprise a series of at tablets arranged in alignment one behind the other, bearing on their flat surfaces designations corresponding to the clerks keys which they represent. The middle indicator tablet is stationary and bears on both its front and rear surfaces the letter A to correspond with the A clerks key 44, which it represents. The remaining two indicator tablets, one of which is positioned in front and the other in the rear of the A indicator tablet bear on their outside surfaces the letter B to correspond with the B key 43, which they represent. The B indicator tablets are normally in unexposed position and when elevated to exposed position will completely conceal the stationary A indicator tablet from View.

The A indicator includes a tablet 2|9 (Fig. 10) integral with the upper end of a rod 220 (Fig. 1) which is loosely supported in guide plates 22| and 222 fast to the cross frame 35, in Order to prevent lateral movement of the indicator tablet. 'Ihe A indicator tablet 2|9 rod 220 are held stationary by a notched plate 223 secured to an ear 224 integral with and projecting rearwardly from the rod 229, which notched plate 223 embraces a cross bar 225 supported at both ends in the cross frame 35.

The B indicator includes tablets 2|8 (Fig. 10) integral with the upper ends of rods 226 and 221 both of which rods are loosely supported in the guide plates 22| and 222 to prevent lateral movement of the same, The rods 226 and 221, one on each side of the rod 220, are joined together by a pin 228 in order that they may be moved as a single unit. The rod 221 is longer than the rod 226 and is adapted to be elevated by the rear end of the lever |24, whenever the machine is operated to register in the B t0- talizer. It will thus be evident that when the B indicator rods 226 and 221 are elevated their tablets 2|8r will completely conceal from View both sides of the A indicator tablet 2|9 and at the same time indicate that a transaction has been entered into the machine by the B clerk. The means for retaining the B indicator rods and their tablets in elevated positions and for releasing them during a subsequent 0peration is shown in the patent to Green, No. 1,920,374, heretofore referred to.

Drawer releasing mechanism The present machine is provided with a plurality of cash drawers 234 and 235 (Fig. 2), one associated with each clerks key. The reason for having a plurality of cash drawers in the machine is to provide a separate receptacle for each clerk, thereby enabling the proprietor to place individual responsibility for errors and shortages, and also to prevent one clerk from fraudulently withdrawing from the cash drawer money in charge of another clerk. The proprietor is able to learn whether the proper amount is in each clerks cash drawer by comparing the cash in the drawer with the amount standing on the totalizer associated therewith.

The drawer 234 is assigned to the A clerk, while the drawer 235 is used by the B clerk. The A drawer 234 is normally selected to open when any of the amount keys alone are depressed, while the B drawer 235 is adapted to be selected and opened by the depression of the B key 43. However, locking of the A clerks key 44 against operation actuates means for effecting the automatic selection of the B cash drawer 235 when any of the amount keys alone are depressed.

The cash drawers 234 and 235 (Figs. 1 and 2) are provided with latches 236 and 231, respectively, each of which latches is pivoted between a pair of lugs 238, only one of which is shown, attached to the rear ends of the cash drawers. The rear ends of the latches 236 and 231 are normally drawn upward by coil springs 239 (only one of which is shown). rllhe drawers 234 and 235 are held shut by the latches 236 Aand`231 hooking, over stationary bars 248 and 24|, respectively, mounted in an auxiliary frame 242 secured to the base of the drawer casing 3|; Associated with the latches 236 and 23'! are levers 243 and 244, respectively, see also Fig. 3, pivoted at 245 and 246 to the auxiliary frame 242. The levers 243 and 244 are under tension'of springs 241 and 248 and when rocked against the tension of such springs serve torelease the latches 236 and 231 from the bars 246 and 24|, respectively, thereby p'ermittingtheir respective cash drawers to be ejected from the drawer casing Y3|Y by means of the usual coil springs (not shown here).

The means for releasing the cash drawers comprises a vertical shaft 249 guided by a lug 233 of the auxiliary rframe 242. The vertical shaft 249 carries a notched disk 256 having sections 25| and 252 which are adapted to cooperate with Vthe levers 243 and 244, respectively, to eifect theA release of the cash drawers 234 and 235. The section 25! is normally positioned directly under the inner end of the lever 243 associated with the latch 236 for the A cash drawer 234.

WhenV the sectionV 25| is in this position, the' section 252 isY positioned slightly to the rear of the lever 244 associated with the latch 231 for the B cash drawer 235. It will thus be seen thatV uponfupward movement of the shaft249 the section 25| of the disk 258 will contact'with the end of the lever 243 and rock it to disengage thelatch 236 from the bar 249, thereby 'releasing the A cash drawer V234. The means for moving the vertical shaft 249 upwardV will now be described. i

The upperV vend of the shaft 243 extends through an apertured lug 254 formed at 'the 'lower end of a link 253. Mounted on the shaft 249 is a xed collar 21| against which the lug 254 bears when the shaft 249 is lifted upwardly;Y The upper end of Ythe link 253 is connected to a lever 255 pivoted to a lug 256 integral with the base 32. Pivoted to the lever 255 is a by-pass pawl 251 which is normally spring pressed against a pin 258 on the lever 255 by a compression spring 259 extending between the pawl 25'! and a lug 268 on the lever 255. The keyrcoupler 4'! is provided with adepending Yprojection 25| which, when the coupler is raised during an operation ofthe machina bears against and rocks the pawl 251 until it clears the top of the pawl, thus ypermitting the pawl to return to its normal position. As'the key coupler 4'! descends,

upon the up stroke of the keys, the projection 26| contacts the upper ,end of the pawl 251 and the rpawl and the pin 258 rock the lever 255 clockwise to raise the link 253 and lift the vertical shaft 249. When the shaft 249 Vis thus lifted, thev section 25|.of the notched disk 258 contacts and moves Vthe lever 243 against the tension of the spring 241, thereby releasing the latch 236 forthe A cash drawer which is then ejected from the casing by the usual coil spring.

The means will now be described for effecting the release of `the "B cash drawer 2,35. Pivotallyv mounted at 26,2.'(Fig. 1) to a bracket (not shown) secured to the auxiliaryY frame 2421s a lever 263 the upper end of which cooperates with pins 2,64 and 265mcunted on the lever |24 associated with the B key 43. Thelower end of the lever 263 extends through an opening in one end of a lever 236 plvoted at 261 to a bracket 268 secured to the auxiliary frame 242. The other end Vofthe lever 266 carries a downwardly extending fast to the lower end of the vertical shaft 249.

It will thus be seen that when the rear end of the lever |24 associated with the B key`43 is raised, the pins 264 and 255 rock the lever 263 counterclockwise which rocks the lever 266 and the latter rotates the arm 216 and shaft 249 clockwise (Fig. 3). Such clockwise movement of the shaft 249 moves the section 25! of the disk 258 from beneath the lever 243 and moves the section 252 directly under the lever 344 associated with the Y Adjustable control means As hereinbefore mentioned, 'each of the clerks keys is `provided with an individual lock whereby the clerks, when going olf duty, may lock their respective keys against operation. Should Vall of thevclerks happen to be off duty at a particular time and the machine be locked against operation by the clerks key locks above mentioned, the proprietor Vwould be unable to depress therkeys and operate the machine in the usual manner without using duplicate keys to the clerks key locks. Tov enable the proprietor'to have complete control over the clerks keys when they are locked againstVVV operation, Vadjustable control Vzo means is provided which when moved-to a certain Y one of its various positions of adjustment will not only release the locked clerks keysfor operation but will eifect the automatic selection of the A totalizer andy its associated devices for operation whenever any of the amount keys alone are depressed. Y Y

.Pivotally mounted on the key rod 45 (Figs. 1 and 6) is a bell crank 211, an upwardly extending arm 218 of which is provided with a, stud 219 of suicient length to engage shoulders 288 and 28| on the lower portions of the locking levers |46 and |54, respectively. Secured to the shaft 88 is a cam 282 in the path of the lower arm of' the bell crank 211. When the shaft 66 is rotated theV stud 219 contacting with the shoulders 286 and 28| of the locking levers |46 and |54 forces said levers counter-clockwise until the arcuate slots therein are in the paths of the studs |58 and |51 carried bythe clerks keys "43 and 44, respectively. When the parts are in theseV positions the clerks .keys may be depressed irrespective `of whether both of the bolts |41 and |55 ofthe clerks key locks haverbeen projected'to Veffectthe locking of said keys against operation.

. The shaft 88 and cam 282 are rotated by'ad. justable controlmeans comprisinga lever 283 pivoted on the shaft 61 (Fig. 6). VThe lever 283k has formed at its lower end Ya gearsector 284, while atY its upper end it is providedV with la rearward extension 285 and a forward extension 286. The extension 286 carries a shouldered stud 281 adapted to coact with the upper edge of a notched plate 288 secured to the side frame 34, for the purpose of keeping the lever 283 in'alignment with the notched plate 288 whenever it is moved to its various positions of adjustment. Fastened to the extension 285 is arlock 289 having a rotatable barrel 299 fast tothe lower end of which is alocking arm 29|. Pivoted at 292 on the lever 283 is a retaining pawl 293 carrying a stud 294 which is normally spring-pressed into engagement with any one of a series of notches formed in the under side of the notched plate 288 by means of a spring 295 fast at one end to the pawl 293 and at its opposite end to an ear 296 formed in the lever 283. Each one of the notches formed in the plate 288 represents a different position of adjustment of the lever 283. The stud 294 on the pawl 293 is adapted to ratchet in and out of the notches of the plate 288 and thereby act as a retainer for the lever 283 when it is moved to each of its various positions of adjustment.

The lever 283 may be locked in any one of its various positions of adjustment by a key 291 for the lock 289. Turning the key in a clockwise direction rotates the barrel 290 and locking arm 29| clockwise to a point where the locking arm 29| is positioned directly above nger 298 on the retaining pawl 293. It will thus be evident that should an attempt be made to move the lever 283 to another position of adjustment the stud 294 is prevented from moving out of its engaged notch by the contact of the iinger 298 with the locking arm 29|. The barrel 290 of the lock 289 is so constructed that the key 291 cannot be removed therefrom unless the barrel is in locking position, thus making it necessary to always lock the lever 283 in one of its positions of adjustment before removal of the key from the lock can be effected.

Provided on the outside surface of the cabinet 39, adjacent a slot (not shown) through which the lock barrel 290 attached to the control lever 283 projects, is an index identifying the various positions of adjustment to which the lever 283 may be moved. This index is represented in the drawings (Fig. 6) by the notations designating various notches in the plate 288.

When the lever is moved to its uppermost position, identied by the word Reset, the machine is conditioned for printing the totals standing on the totalizers and resetting the tctalizers. When the lever is moved to the Unlock A & B position the locked clerks keys are released for operation and the machine is conditioned for automatic selection of the A totalizer and its associated devices for operation whenever any of the amount keys alone are depressed. When the lever is moved to the Closed drawer position the machine is conditioned s0 that it cannot be operated unless the cash drawers are closed. With the lever in the Open drawer" position the machine is conditioned so that it can be operated while the cash drawers are open. When the lever is moved to its Lock register position the machine is locked against operation.

When the lever 283 is moved to the Unlock A & B position, the locked clerks keys are released for operation and the A totalizer and its associated devices are automatically selected for operation whenever any of the amount keys alone are depressed. The means for accomplishing this will now be explained in detail.

Mounted loosely on the key rod 45 is a gear sector 304 meshing with the gear sector 284 on the lever 283, and secured to the gear sector 304 is a gear 305 meshing with a gear 306 secured to the right hand end of the shaft hereinbefore mentioned. From the foregoing it is evident that when the proprietor manipulates the lever 283 so that it is set in the Unlock A & B position the shaft 80 will be rocked by the train of mechanism just described to actuate the cam 282 to disable the locking levers |46 and |54, thereby releasing any locked clerks keys 43 and 44.

As previously mentioned, the machine is normally conditioned for automatic selection of the A totalizer and its associated devices for operation when any of the amount keys alone are depressed. However, the locking of the A totalizer selecting key 44 against operation renders effective means for automatically selecting the B totalizer and its associated devices. When both of the clerks keys 43 and 44 are locked against operation, it is necessary to provide means, under the control of the lever 283, when it is moved to its Unlock A & B position, to render ineffective the means for automatically selecting the B totalizer and its associated devices, in order to permit the normal automatic selection of the A totalizer and its associated devices. The means for accomplishing this result will now be described in detail.

Secured to the shaft 80 is a box cam 301 (Fig. 5) provided with a raceway 308 cooperating with a stud 309 carried by the rearwardly extending arm of a bell crank 3| 0 pivoted on a rod 3|| supported in the side frames 33 and 34. When the lever 283 is moved to its Unlock A & B position, it rotates the shaft 80 counter-clockwise, through the train of gear mechanism previously mentioned (Fig. 6), and thereby causes the box cam 301 to rotate counter-clockwise (Fig. 5).

Such movement of the cam 301 rocks the bell crank 3|0 counter-clockwise. Ihe bell crank 3|0 has an ear 3|5 carrying a pin 3| 4 cooperating with a slot 3|6 in the arm |66. The coupling slide |61 is tapered at its upper end to provide l suflicient clearance for the stud |60 so that the slide I6| can be adjusted by the lever 283 independently of the lever |53. Therefore, when the bell crank 3|0 is rocked counter-clockwise, the arm |66 is rocked clockwise to lower the coupling slide I6| to a point where its tapered end permits sufiicient clearance for the stud |60 to be moved rearwardly by the upwardly extending arm of the bell crank 3|0 to uncouple the slide |6| from the key coupler 41. In this manner the automatic selection of the B totalizer and its associated devices is prevented, and the machine is conditioned for automatic selection of the A totalizer and its associated devices.

Operation A summary of the operation of the above described devices and the manner in which they operate so as to enable the machine to be operated on an automatic open keyboard with respect to registering in one totalizer, and on an optionally open keyboard with respect to registering in another totalizer, will now be given.

The illustrative machine is provided with two totalizers, each of which has associated therewith a totalizer selecting key. A plurality of lockcontrolled devices is provided, one for each totalizer selecting key, for' locking the keys and their associated totalizers against operation.

In the present machine the A totalizer and its associated devices are normally automatically selected for operation whenever the machine is operated by depression of any of the amount keys alone, thus permitting the machine to be operated on an automatic open keyboard with respect to the A totalizer and its associated devices.

The B totalizer and its associated devices are normally selected by depression of its corresponding totalizer selecting key. However, automatic selection of the "B"totalizerlandits arssociated devices may be effected by simply locking the fA totalizer selecting key, through its respective lock-controlleddevice, against operation. Under such an arrangement the machine may be operated on an optionally open keyboard with respect toL the VYB totalizer and its associated devices. A

Y`froin the above it will be apparent that when one totalizer is locked against operation, through the lock-controlled device for its respective totalizer selecting keygitk effects the automatic selectionigof the othertotalizer and its associated Y devices for operation Whenever the machine is operated by depression of any of the amount keys alone.V` Y Y ,From the foregoing it is apparent that the illustrative machine-is especially adapted for use in plzlilczes' of business'operatingon both day and night shifts. For example, the A totalizerrmay be assigned to the clerk employed on the day while the B totalizer may be used by the clerk employedonV the nightv shift. The lockcontrolled devicesfor the totalizer selecting keys enable each clerk, when going off duty, to lock his particular totalizer selecting key and associated totalizer againstoperation, thereby preventing anyk registration being made in his particular totalizer or access to his cash drawer, during his absence. -Inasmuch asthe A totalizer and its associated devices are normally automatically selected fory operation, the clerk on the day lshift may'V operate the machine on an automatic open keyboard with respect to registering in his -particul'ar totali-zer. When the day clerk goes off duty, he locks histotalizer selecting key and corresponding totalizer against operation, such locking operation also serving to condition the machine for automaticselection` of the BA totalizer and its Vassociated devices'. When the clerk employed on the night shift comes on duty, he unlocks his particular totalizer selecting key, thereby releasingA the machine for operation on an automatic open keyboard with respect to the B totalizer and its associated devices.. It sometimes happens that both clerks are absentY at a particular time. and their totalizer selectingA keys are locked against operation, through the lock-controlled devices associatedtherewith, thus locking the machine against operation. On such occasions the proprietor or other authorized person. sometimes wishes to' register 'an vamount into the machine. In order to enable theproprietor orotherV authorized person to: make such a registration, Without the rnecessityl of Vusing duplicate keys to the totalizer selecting key locks, tneadjustable controlpmeans, under'control of lock and key, when moved to itsY Unlock A & B position is` adapted to release the locked totalizer selecting keys and eiectY the automatic selection of the A totalizer and' its associated devices for operation Whenever the machine isA operated by 'depression of any of the amount keys alone. Under this arrangement, the machine may be operated' on an automatic open keyboard with respect to registering inthe A`tota1izer, while depression of the B totalizer selecting Ykey is necessary to select the B totalizer for operation.
